Hi everyone i need help converting 25MMscfd of natural gas to kg/hr i calculated the molecular weight of the natural gas to be 18.94g/mol the feed conditions are 6900kPa and 298K i'm pretty sure 1MMscfd = 1180m^3/hr at standard conditions, I'm not sure how to work this out for the feed...

Hey everyone, I've got a finned surface question I've got a finned wall is constructed of aluminium alloy with k = 150 W/mK. The wall thickness is 2.0 mm and the fins, with a thickness of 2.0 mm, are straight with rectangular profile. The inside of the wall is maintained at a constant...

Hey everyone, This question kind of confused me, i think the general idea is to use y(t) = yh(t) + yp(t) and basically saying yh(t) = Acos2t + Bsin2t to find yp(t) subbing into the differential equation and equating. help much appreciated :)

dy/dt + y = \infty \sumSin(nt)/n^2 n=1 Ok still a bit new with all these symbols and stuff but that is the basic jist of it. y(t) = yh(t) + yp(t) it what i thought about using to start off with, yh(t) = Acos2t + Bsin2t. Then subbing yp(t) into the differential equation. Not really...

dy/dt + y =\infty\sumn=1Sin(nt)/n^2

dy/dt + y = Sigma Sin(nt)/n^2
